in such a case I would use 'jobbsse -level cc2 -setup' first, and then go in the subdirectories and check/modify the $freeze and $atoms data groups.If you use a def2 basis set, it would make sense to freeze 4 shells per iodine, because 14 shells are already in the ECP. Then you have a kr core frozen.For the ghost calculations, only shells from atoms with a charge should be frozen.
